Abstract

See full text

Apparatus for operating a group of normally closed, pressure compensated drippers at relatively low liquid flow rates includes a pulsating device having an inlet and an outlet that converts a low continuous liquid flow rate entering its inlet, through a flow control unit, to a high intermittent and pulsating flow rate ejected through its outlet. A manifold has an inlet connected to the outlet of the pulsating device, a group of normally-closed, pressure-compensated drippers being connected to the manifold. The pulsating device converts a low continuous flow rate of liquid entering its inlet, through the flow control unit, to a high intermittent and pulsating flow rate that ejects from its outlet and flows from its outlet through the manifold inlet and through the normally-closed, pressure-compensated group of drippers connected to the manifold, out from the drippers, at a pressure-compensated low flow rate.
